le buying windows or other woodwork, as in buying any other important 

commodity, we are all seeking the greatest value per dollar invested. Modern 
business has demonstrated that this greatest value can be attained when the 
product is manufactured in quantities. Quantity production, of course, can 
only be obtained by limiting the output to certain sizes, certain woods and 
certain patterns, all of which have been adopted as standard after long ex- 
perience in meeting the needs of homebuilders. 


In the design of windows and sash, as well as in the design of all Curtis Wi6dd- 
work, the cooperation of a representative section of the architectural profession 
has been sought. Their suggestions have been applied to the several problems 
of design, materials, construction methods and workmanship. 


The complete line of Curtis Woodwork is produced on this basis, and therefore 
represents the maximum value that you can get for your woodwork dollar. 
Each window shown in this section of the Curtis Catalog No. 500 is made in 
quantities (except where otherwise specified). These are ready for shipment, 
subject to prior order, in White Pine in the sizes listed. The face measurements 
of stiles and rails, as an aid to the selection of appropriate hardware, are listed 
on the various pages where required. 


Naturally, in different sections of the country, local demand varies. For that 
reason, complete stocks of all designs and sizes of windows or other items of 
woodwork are not carried by all Curtis plants and all dealers. You can be 
assured, however, that any material you select from the Curtis Catalog No. 500 
is available for immediate shipment from one of the Curtis factories. If your 
woodwork dealer does not have in his own stock the particular piece of wood- 
work you select, he can consult his Curtis Catalog Supplement and tell you 
from which factory your order can be shipped, how quickly, and the price. 


The sizes listed on each page are those which are made in large quantities, 
with resultant lower cost. Obviously, you will get prompt service and guaran- 
teed unvarying quality when you order from these lists. On material which is 
‘‘odd’’ as to size, design or wood, quantity savings cannot, of course, apply.

W hat Makes Curtis Windows Better? 


H*%5 you ever wondered what it is that makes one brand of windows better than another? Why should 
you trouble to look for the Curtis trademark on the windows you buy for your house? Of two windows 
which may look very much alike, what is the difference that makes the Curtis product the wiser buy? 


If you were to go through the sash department in one of the Curtis factories, your interest would be aroused 
by some of the operations which are shown in the photographs on these pages. As you paused to watch 
these processes and follow the Curtis window in its making, your question would be answered—why Curtis 
windows are better. 


After seasoning, the lumber that is to be used in making Curtis doors and windows goes first through the 
cutting department, where it is cut to usable widths and lengths. Then it goes through a planer to be sur- 
faced to an even thickness, and is then sorted according to the use that is to be made of it. Longer and 
wider pieces go to the door department, while narrower and shorter pieces are used in window-making. 


T HE first operations in making Curtis windows are to cut the 
pieces of wood to exact lengths, and to make the mortises 
(slots) and tenons (tongues) which hold the wood parts firmly 
together. The tenoning of the bottom rail is performed on the ma- 
chine at the left, called a@ “‘double-end tenoner,”’ because it 
machines both ends of the stock at the same time. On the machine 
below, through-mortises are cut in the stiles, to member with the 
tenon of the bottom rail. Slip-mortises are cut in the stiles (the 
vertical wood parts), to member with the top and check rails, 
forming a joint that, when pinned, will resist the upward and 
downward thrust of 
opening and closing the 
window. 

Only the bottom rail of 
the bottom sash has a 
through-tenon instead of 
@ slip-tenon, for still 
greater strength at a 
needed point as shown 


at the left. 


T HE Curtis rabbeted check rail described on pages7 
and 10 is made on the machine directly below, which 
also molds the rail to receive the glass. Small wood bars 
which divide the glass into smaller panes are molded in 
a similar way. In windows which are to have these 
smaller panes, the chisel mortiser, below at the right, 
cuts holes in the stiles and ratls to receive tenons on the 


dividing bars and hold them firmly. 


ee 


HE process of cutting the groove for the sash cord 

and boring the hole for the knot is accurately done on 
the machine directly above. 
The completely machined sash stock is trademarked. To 
give the customer the advantages of quantity production, 
even on small orders, large quantities of machined sash 
material are always carried in stock. 
Assembling sash material into windows of the required 
size and design, as shown at the right, is followed by 
placing each window into a clamp to hold it securely, 
while steel dowels are driven and set on the machine di- 
rectly below. This is called ‘’ pinning.”’ 


| BN IED the window is sanded, ready for your 
painter without further labor on the job. A special 
machine, shown below at the left, smooths the check rail 
and both sides of the sash in the same operation. 
Curtis windows are furnished either glazed or unglazed. 
When glazed at the Curtis factory, zinc ‘‘ points’ are 
driven into stiles and rails to hold the glass and then 
putty is applied. Both operations are shown directly 
below. The special groove, described on page 16, provides 
additional anchorage for the putty. 
These are some of the operations which enter into the 
construction of a Curtis window before it comes to you.

Keeping the Heat In 
and the Cold Out 


fe 


A WINDOW has two functions: 
to admit light, and to provide ven- 
tilation. To accomplish these two 
purposes, windows must be made 
with the utmost care. 


From the standpoint of weather 
resistance, the weakest point of a 
window is the check rail—where 
the upper and lower sash come to- 
gether. This is a place for wind to 
blow through and for heat to escape, 
when the sash come together in a 
straight or even a beveled line, as in 
ordinary windows. 


Curtis engineers, after much experi- 
mentation, evolved the rabbeted 
(notched) check rail shown below 
in cross section. Seven times as 
much wind pressure is required to 
pass through this rabbeted meeting 
rail as through plain ones.

on page 6 have been long in general use and 
are retained in this catalog because of their 
popularity. Wherever inexpensive but 
well-made windows are wanted, either of 


alee term ‘“‘double-hung’’ is applied to 
windows composed of two separate slid- 
ing sash, as distinguished from casements, 
which swing, in or out. The windows on 


this page and page 6 are double-hung win- 
dows. The panes of glass are called “‘lights.”’ 
Thus on page 6 are shown the two-light and 
the four-light window, and on this page the 
eight-light window. 

Two-light windows are much used, for all 
kinds of buildings. Both C-2502 and C-2504 


these can be depended upon for durability. 
Window C-2508 on this page is a tall, narrow 
opening of excellent proportions, for small 
wall spaces. These are especially desirable 
also for grouping, producing an effect similar 
to casements. Often these windows are used 
as side units in bays.

Wood ‘Dividing ‘Bars 
Add to Good Looks 


ofp 


Oxs of the many important de- 
tails that make a Curtis window 
good-looking is the use of wood 
bars or muntins that divide the glass 
into smaller panes. In the cross sec- 
tion below, the lined portion is the 
wood bar. The glass coud is fitted 
against the notch in the bar and held 
in place with zinc brads and sealed 
with putty (dotted) on the outside 
of the window. Note the pleasing 
molded outline of the muntins in- 
side the window. They are narrow 
in order not to obstruct the light, 
but deep, to give character to the 
window. Where these bars meet 
other wood parts of the window, 
they are held with a tenon joint. 
Muntins of this kind in Curtis win- 
dows give them an unusually attrac- 
tive and finished appearance.

for such good-looking designs as this twelve- 
light double-hung window. It has been ex- 
ceptionally popular, especially for Colonial 


N | UCH of the appeal which attaches to old 
houses of every country is due to their 
small-paned windows. The small lights with 


their painted wood dividing bars carry out 
the other structural lines of the building. 

In recent years there has been a revival of on 
preciation among homebuilders for these di1- 
vided-light windows. Architects and interior 
decorators always favor them. The increasing 
demand for windows of this sort is responsible 


work. It is made up with lights of different 
sizes, thus securing openings of different 
widths and heights. It is always best to have 
the windows in a house uniform in size as 
far as possible. Windows C-2508, page 7, and 
C-2516, page 10, may be used when wider or 
narrower windows are required.

Curtis Frames Increase 
the Coxiness of the Home 


ote 


Your windows can be only as 
weatherproof as the frames which 
hold them in the walls. Curtis frames 
have many distinctive weather- 
resisting features. Below is a sec- 
tion through the sill of a Curtis 
frame. Both the sill and the lower 
edge of the window slope to the out- 
side, to shed water. At the inner 
point, where they meet, there is a 
rabbet (notch) in the sill (A). Your 
carpenter bevels the bottom of the 
sash to fit this notch and the bevel 
of the sill. This tight joint prevents 
wind or rain from beating in, under 
the window, and at the same time 
acts as a wedge to hold the window 
more tightly in the frame. Another 
notch (B) provides a shoulder 
against which the screen, shutter or 
storm sash fits snugly.

INe single feature of the exterior does more 
to make or destroy the good appearance 
of a house than the windows. Whatever its 
type, a house with windows poorly propor- 
tioned, badly placed or ugly in design cannot 
be successful. Great care should be taken in 
selecting suitable windows. Here is a com- 
panion design to the window on page 8. This 
is a twelve-light circle-head window to be 
used in houses with round-topped openings, 
such as those of Spanish or Italian influence. 


These Curtis windows at once lend distinction 
to a building and lift it out of the ordinary. 
Notice the arched top, which is a perfect 
semi-circle, both in the glass and wood por- 
tions of the window. The curved wood top 
rail is made of two pieces of wood, in each of 
which the length is with the grain of the 
wood for greater strength. 

Curtis citcle-head windows are made with 
the same construction features that have made 
all types of Curtis windows so satisfactory.

Ir is said that one-fourth of the 
fuel burned in the average house is 
wasted, due to window leakage. 
The weakest point of most windows, 
from the standpoint of weather 
resistance, is the check rail or meet- 
ing rail, where the two sash come 
together. Here there is a chance for 
the escape of heated air and the 
leakage of cold air and of water 
which will destroy the comfort of 
the house and ruin walls and dra- 
peries. 


Curtis windows are strengthened at 
this point by a rabbeted (notched) 
check rail devised in the Curtis fac- 
tories. This rabbeted check rail is 
shown in cross section in the detail 
below. Comparing it with ordinary 
windows, as shown in the detail on 
page 11, you will see how effectually 
the Curtis rail guards against leak- 
age of wind and rain.

WINDOW C-2516 


Gye of the new Curtis designs is this 
sixteen-light window. Its satisfying 
proportions hold good in any of the sizes 
listed below. 

The sixteen-light window is a reproduction 
of those found in many houses of Revolu- 
tionary times. A large window is often de- 
sirable either for furnishing extra light to the 
interior, or for architectural effect. The use 
of small panes in this Curtis window fills the 
need for large glass area, without losing good 
appearance and uniformity of design. Since 
the panes are of similar size to those in other 


Curtis windows, a harmonious effect can be 
carried out throughout the house, regardiess 
of the size of the openings. This matching up 
of patterns is just one of the fine points of 
Curtis manufacture that make it well worth 
while for the homebuilder to select Curtis 
Woodwork. 

The Curtis trademark on windows assures 
you of design that is architecturally correct 
and guarantees that they are made with Curtis 
methods—which means durability, ease of 
operation and long life. Look for the Curtis 
trademark on the windows you buy.

How Curtis Rabbeted 
Check ‘Rail Saves Coal 


die 


Tas sketches below show two 
common methods of making the 
meeting rails of double-hung win- 
dows (where the two sash come to- 
gether at the center). Figure A shows 
the simpler method. Obviously it 
offers little resistance to leakage of 
air or water from gusts of wind or 
driving rain. Figure B shows the 
common beveled joining, which is a 
step in advance, but which is still 
far from weather-proof. 

The Curtis rabbeted check rail, a 
Curtis feature, shown on pages 7 
and 10, is more nearly weather-tight 
than either of these. Looking at 
these diagrams, it is not hard to 
understand how rain and wind that 
could force a way through such rails 
as A and B, would be turned aside 
by the rabbeted Curtis check rail.

Made with Extra Care, 
Curtis Windows ‘Work’ 


sip 


V INDOWS that won’t ‘“‘work’’ 
have destroyed many a good temper. 
Extra care taken in machining Curtis 
windows insures ease of operation 
and lasting service. The figure below 
shows the cleanly cut groove and 
double groove for the sash cord and 
bore for the knot. These are accu- 
rately machined at the Curtis fac- 
tory, to allow the sash toslide freely, 
and to hold the cord in its place. 
They are ready for the workman on 
the job without further fitting. 
The check railis tenoned, or tongued, 
to fit the slot in the stile. This joint 
is reinforced with steel dowel pins 
so that it cannot pull apart when 
the window is shoved up or down, 
as would a butt joint or a miter.

WINDOW C-2556 


Viens with small panes in the upper 
sash and a single large pane in the lower 
sash are called ‘‘top-divided”’ windows. They 
represent a compromise in design between the 
two-light window and the window with 
both sash divided into small lights. In Win- 
dow C-2556, the upper sash is divided into six 
rectangular lights, while the lower sash is a 
single light. 


Top-divided windows are popular with home- 
builders, particularly for houses which do not 
follow any definite period in architecture. 
Though primarily intended for light and ven- 
tilation of the interior, windows are an im- 
portant element in the appearance of the 
building as a whole, giving it a touch that is 
good or otherwise, according to whether the 
windows are well selected.

Te only difference between Win- 
dow C-2563 and Window C-2564 is 
in their width. Window C-2563 is 
made in glass widths 26 inches or 
less, with three panes in the upper 
sash, while Window C-2564 is made 
in glass widths 28 inches or more, 
and has four panes in the upper sash, 
in order to maintain the same har- 


monious proportions for windows 
of various sizes throughout the 
house. 


WINDOWS C-2563 and C-2564 


ee narrow panes lend height to short 
windows or low-ceilinged rooms. Follow- 
ing no specific architectural type, this style is 
suitable for a wide range of building uses. 

Windows and their frames are an important 
factor in the interior comfort of the home. 
Openings which let the wintry blasts shrill 
in, which let you ‘‘heat all outdoors,’’ which 


admit rain and dust to spoil your walls and 
draperies—such windows may cost a little 
less (at first) than windows bearing the Curtis 
trademark, but they will be a constant re- 
minder that such economy doesn’t pay. 

The difference between the best and the poor- 
est windows you can buy is not great in dol- 
lars and cents, and is a wise investment.

Warn roperly fitted with 
modern hardware and Curtis frames, 
casements are tight against the 
weather. When casements are not 
weatherproof, it is more often the 
fault of the frame than of the sash 


itself. Curtis casement frames have 
weatherproof features which mean 
much to your comfort. 


CASEMENTS C-2703 and C-2706

ee of sliding up and down, as regular 
double-hung windows do, casements swing 
from hinges. The weight of the casement is 
therefore supported entirely by the hinges, 
and in order that this strain may not be too 
great, casements are relatively small, and tall 
rather than wide. Their proportions are dif- 
ferent and interesting, and lend themselves 
especially well to grouping, producing the 
low, wide effect that is so often desirable. 
Rectangular casements, like those pictured 


here, may be used singly or in pairs or groups, 
to afford any desired amount of glass area. 

There has always been an artistic appeal about 
casements. Some types of houses seem incom- 
plete with any other kind of windows. Case- 
ments may be appropriately used in any type 
of house, and are often an added element of 
charm. The choice between casements and 
double-hung windows is often a matter of per- 
sonal preference. Design C-2703 is especially 
adapted to Italian and Spanish architecture.

CASEMENT C-2708 


An outstanding advantage of casements is the 
fact that, as they swing on hinges, they may 
be opened their entire area, while the double- 
hung window cannot be opened more than 
half its area. Casements look well in groups, 
and provide maximum ventilation. 

For the English cottage or Tudor house, 
nothing could be more effective than Case- 
ments C-2708. Proper hardware itisures ease 
of operation, and solves the problems of 
screening and curtaining. 


ROM either the interior or the exterior of 

the house, casements are effective and 
beautiful. Well-designed windows, such as 
Casement C-2708 shown on this page, are in 
themselves decorative and need very little 
draping. Wood dividing bars with molded 
outline are one of the attractive features of 
Curtis casements. The best effect is secured 
by painting these muntins white on the ex- 
terior, and finishing the interior to accord 
with the trim in the room. 


Putty Seals Joint Be- 
tween Wood and Glass 


oe 


in Curtis windows and casements, 
the glass panes are securely fastened 
with zinc ‘‘points’’ and puttied on 
the outside. The putty protects the 
wood from rotting due to water 
trickling down along the glass and 
seeping in. The photograph below 
shows a cross section of the bottom 
rail of a Curtis window or sash. Stiles 
(the upright wood parts) are puttied 
in the same way. Curtis windows 
have a special putty groove (sce 
diagram), which forms a ‘‘key’’ or 
additional anchorage -to hold the 
putty in place and prevent it from 
loosening. Only the most depend- 
able putty procurable is used in 
making Curtis windows and sash.

Curtis Window Joints 
Won't Pull Apart 


sk 


(Tuer are several ways of join- 
ing two pieces of wood—the miter, 
butt, dowel, dovetail, mortise-and- 
tenon, glue and other joints, each 
suited for special purposes. Of these, 
the mortise-and-tenon is selected as 
best for holding together the stiles 
and rails of Curtis windows. 


As shown in the photograph below, 
each stile is mortised to receive the 
tenon of the rail. This joint is fur- 
ther strengthened by cross-pinning 
with two steel pins. 


This point is only one of the many 
features of Curtis windows that in- 
crease their lasting qualities and 
their good looks. Windows made 
with so much care are bound to be 
durable and to resist hard usage. 
That is why the wise homebuilder 
looks for the Curtis trademark on 
windows and sash. 


CASEMENTS C-2714 


QO of the newest types of windows is the 
circle head, which is already proving 
popular with homebuilders, both for double- 
hung windows and for casements. These har- 
monize with the rounded doors and archways 
that are much used in Spanish and Italian de- 
signs, especially on the first story. Nothing 
could be more in keeping with these styles 
than the handsome casements pictured on this 
page. They are distinctive enough for the 
large residence, and will add interest to any 
building. 

Notice the perfect symmetry of the rounded 
top, which 1s a true semi-circle. The curved 


wood portions, both of the window itself and 
of the trim around it, are cut with the grain 
of the wood lengthwise for greater strength. 
These casements are furnished in pairs, and 
are tabbeted. 

The smaller size is suitable for use with six- 
light casements (8 by 10-inch panes); and the 
larger size is suitable for use with eight-light 
casements (10 by 12-inch panes). 

The trim which frames a window has a great 
deal to do with the general effect of the in- 
terior. This is especially true when openings 
such as thése are used, which are unusual in 


design and shape.

Avoiding Window Troubles 


INDOWS sometimes stick or rattle as a 

result of not being properly fitted, or 
from swelling or shrinking, due to too much 
or too little moisture. Several simple precau- 
tions may be taken to avoid these troubles. 
When windows are delivered to the job, a 
suitable priming coat should at once be ap- 
plied to stop the absorption of moisture. As 


windows are set in place before the building 
is entirely dry, the wood parts are bound to 
swell to some extent. For that reason, it is 
not wise to fit them to operate too freely at 
first; otherwise when they become properly 
seasoned in the normal atmosphere of the 
home, they may become too loose. Windows 
should be primed as soon as delivered.

of the Rockies, there is a Curtis dealer who 
can give you complete information, including 
prices, shipping points and time of delivery. 
In larger cities, especially, there are Curtis 


dealers who have many items of Curtis Wood- 
work in their own stock and on display in 
their display rooms, so that you may see the 
actual woodwork you are buying. 

If you do not have a regular dealer, write us 
for the name of the nearest dealer who sells 
Curtis Woodwork.
